1) Cut Jab's energy cost in half.
2) Cut energy regeneration in half.
3) Increase maximum Chi to 8 (10 with Ascension).
This would accomplish a couple of things. It would allow for more burst since you can stack enough Chi for 4-5 Blackout Kicks instead of just 2, and it would also allow for a little more breathing room in the rotation and a break away from Jab-BK Jab-BK Jab-BK, which is 80% of Windwalkers gameplay. It would also penalize you less for being off target, since it will take longer to overcap energy.
